Hi there, I noticed that it was common that a size bigger would most likely fit on a 2006 road king custom from its original size. But I was wondering if you or if anyone has had to make any type of modifications to the belt or any of the parts by the rear wheel area. I wish to research this before making the expense...Also can radial tires be used?

Yes. You can use a radial on the rear.
Can't tell you for sure if you can go one size wider but as a general rule it's ok to do. If you want to be sure you can check the clearance with your existing tire, measure the tire width, and figure out how wide you can go. Then go down to the shop where the tire is and measure it to be sure.
Before taking that as gospel, visit the tyre maker of choice and check their recommendations for your model! It is true they seem to mix tyre types more these days than of old. It is all very well for us novices out here to think things like that, but the experts are the tyre firms. If it will help email them with specific questions about their tyres.

I have just fitted a 2007 swingarm with 2005 wheel to my old Glide, along with a 150 Avon Venom. There is plenty of room with the later spec narrow belt to get the belt guard in as well. Beware however that the nominal width of any tyre is probably different to its fitted width. I estimated that I could get my earlier wide belt in with the 150, but it didn't work out, because the 150/80 was actually wider than on Avon's website. Some tyres are stated as being significantly wider than their nominal size.
